Speed Optimizer < 7.8.5 - Admin+ Stored XSS via DNS Prefetch and Font Preload URL Lists PUBLISHED

Description (CNA)

The Speed Optimizer WordPress plugin before 7.8.5 does not sanitise or escape some of its settings before outputting them in the head of front-end pages, which could allow high-privilege users such as admins to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in a multisite setup).
